Testing the Number of Neutrino Species with a Global Fit of Neutrino Data
Manuel Ettengruber, Alan Zander, Philipp Eller
We present the first experimental constraints on models with many additional neutrino species in an analysis of current neutrino data. These types of models are motivated as a solu…

Consequences of Multiple Axions in Theories with Dark Yang-Mills Groups
Manuel Ettengruber, Emmanouil Koutsangelas
General consistency requirements of Quantum Gravity demand the existence of one axion per Yang-Mills group. In this work, we consider theories with dark Yang-Mills sectors and inve…

Discovering neutrinoless double-beta decay in the era of precision neutrino cosmology
Manuel Ettengruber, Matteo Agostini, Allen Caldwell +2
We evaluate the discovery probability of a combined analysis of proposed neutrinoless double-beta decay experiments in a scenario with normal ordered neutrino masses. The discovery…
